ANSON WARREN AND J AMES W. MARTIN, OF lVIAQUOKETA, IOVAQ IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 35,794, dated July 1, 1862.

To aZZ whom it may concern.-

Be it known that we, ANsoN WVARREN and JAMES W. MARTIN, both of Maquoketa, in the county of Jackson and State of Iowa, have invented a certain new and useful Improvement in \Vater-Elevators; and we do hereby declare the following to be a full and exact de scription of the same, reference being had to the accompanying drawings-making a partof this specification, in which- Figure 1 is a vertical longitudinal section of our saidinvention at 00 00, Fig. 2. Fig. 2 is an end elevation of the same with a portion of the frame removed, so as to expose the interior. Fig.3 is a perspective view of one of the spiral guides, hereinafter described.

Similar letters of reference indicate corresponding parts in both views.

Our invention relates to that class of waterelevators in which two buckets are employed, one descending empty while the other rises full, and in which each bucket, as it rises to the top, is automatically turned in the right direction and its contents discharged by an automatic valve.

Our improvement consists, first, in an improved arrangement of parts whereby the buckets are held at the necessary distance apart and turned into correct position for discharging, the slippage of the cord prevented, and the power required to elevate the full bucket reduced; second, in an improved device'for turning the bucket into the correct position to discharge its contents; third, in an improved combination of devices to incline the bucket and operate its valve so as to discharge the water through the spout in the wellcurb, as hereinafter explained.

To enable others skilled in the art to which our invention pertains to make and use the same, we will proceed to describe its construe tion and operation.

A represents the well curb or frame provided with two spouts, a c,through which the water is discharged, as hereinafter explained.

B is a crank-shaft journaled across the upper part of the frame A and carrying a pulley, C.

D D are pulleys or wheels mounted on shafts d d on each side of the pulley 0. bis the crank by which the shaft B is turned. The cord N passes under the pulley 0 and over the wheels D D, the relative positions of the said pulley and wheels being such as to bring the cord in contact with two-thirds or three fourths of the periphery of the pulley.

E E are the buckets, each provided with a spout, e, and a valve, F, automatically opened by its rod G, coming in contact with a cross beam, L, as the bucket reaches its highest position. The cord is attached to each bucket by.a swivel, H, at the extremity of a horizontal arm, I, projecting from the top of a flat I link, J, which is hinged to the bucket atj.

K K are spiral bow-shaped guides attached to the upper part of the frame for the purpose of turning the ascending bucket to its right position for discharging, as hereinafter explained. The construction of these guides is more clearly shown in Fig. 3. They are so placed that the cord depending from the wheels will pass through them, and the link J as the bucket ascends will turn it in correct position for emptying.

M M are cross-beams, so placed as to depress the inner margin of the bucket,and thus cause the spout e to project over the spout a or a for emptying the bucket.

The operation is as follows: The parts being in the position shown in Fig. 1, the operator observes'at a glance that the bucket E is elevated, and therefore rotates the pulley G in the direction shown by the arrow in order to raise the bucket E. The guide K, coming to a point or an edge atits lower end, presents no obstruction to the ascent of the bucket; but whatever position the link J may have as sumed by the turning of the bucket it will be gradually deflected by the said guide until,

when the bucket reaches its greatest elevation, it is turned to the correct position to adapt the spout e to discharge through the spout a of the wellcurb. The inner margin of the bucket now strikes the cross-beam M, and a continued upward draft upon the cord throws the bottom of the bucket over the spout a,and the valve-rod G, coming in contact with the beamL, raises the valve F andallows the water to flow out. This position of the various parts at this'time will be more clearly understood by reference to the elevated bucket E.

By placing the cord beneath the pulley O and over the wheels D D, which project over the pulley O, the buckets are separated asufficient distance apart without the necessity of using a pulley, O, of large diameter, and at the same time the cord is drawn around so large a part of the periphery of the pulley O as to effectually prevent slippage. We are aware that separate wheels or pulleys-have before been employed to spread the buckets apart without using a winding pulley of large diameter, but are not aware of any instance in which the additional wheels have been arranged in the way we have described so as to draw the cord around the larger part of the periphery of the winding-pulley.

It will be manifest that our invention is equally applicable to water-elevators in which a counterpoise-weight is substituted for one of the buckets.

Having thus described our invention, what we claim therein as new, and desire to secure by Letters Patent, is-

1. The relative arrangement ofthe winding pulley G and wheels D D, constructed as de scribed, and operating in connection with the cord N, guides K K, and buckets E E, in the manner and for the purposes specified.

2. The combination of the spiral bow-shaped guides K K, swivels H, horizontal arms I, and fiat links J, all constructed, arranged, and operating in the manner and for the purposes set forth 3. The combination of the cross-beams L M, automatic valve F G, hinged link J, and spout 6, operating, in the manner explained, to first tilt the bucket and afterward discharge the water through the spout a or a.
